Application filed January 17, 1920. Serial No. 352,057.
To all whom it may concern:
Be it known that I, NATHAN JosIAs, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Combination Saw- Tables and Single-Spindle Shapers, of which the following is a specification.
My invention relates to certain improvements in the combined saw table and single spindle shapers of the type such as that shown in the patent granted to me on the 6th day of January, 1920, No. 1327390; the ob ject of my present invention being to 1mprove the construction of a combined saw table and single spindle shaper of this type, and to provide means for reversing the movement of the spindle. A further object of the invention is to so design the machine that one belt can be used to drive the spindle when it is in either of its two positions.
In the accompanying drawings:
Figure 1, is a side view of my improved combined saw table and single spindle shaper;
Fig. 2, is a plan view;
Fig. 3, is a front elevation of a portion of the table;
Fig. 4, is a view looking at the side of the machine opposite to that illustrated in Fig. 1;
Fig. 5, is a longitudinal sectional view through the standard and table showing the spindle in a horizontal position and the saw mounted thereon Fig. 6, is a view similar to Fig. 5, showing the spindle in the vertical position and a shaping cutter mounted thereon;
Fig. 7, is an end view showing the means for reversing the movement of the spindle;
Figs. 8, 9 and 10, are detail views of the treadle mechanism for the shaper, and V Fig. 11, is a view illustrating a modification.
1 is a standard having a suitable base 2 and side frames 3, and on this base are curved segmental bearings 1 to receive the curved projections 5 secured to the under side of a table 6. In the present instance, one of these hearings 1 is at each side of the standard, and there are two projections 5 on the table, as clearly shown in Fig. 41. 7 is a segmental rack shaped as shown in Fig. 3, and secured to the under side of the table by bolts 8. The teeth 9 of this rack mesh with teeth of a pinion 10 on a spindle 11 having ahand-wheel 12, and this spindle extends through a segmental slot 13 in the segment 7. On the spindle 11 is a clamping nut 11- having a handle 15 which, when the table is moved into position by turning the hand-wheel 12, can be locked to the-standard by the nut 14, as the spindle 11 is carried by a bearing 16 on the standard, Fig. 4-. On the segment 7 is a scale plate 17, and on the standard is a pointer 18 so that when it is desired to shift the table to an angular position, the gage plate will indicate the angle, and the table can be locked in the position to which it is adjusted.
On the standard 1 is a vertical slide 30 carrying a pivot pin 19, on which is mounted a frame 20 carrying a spindle 21 whlch, when in the horizontal position, as shown in Fig. 5, acts as a saw spindle, and when in the position shown in Fig. 6, acts as the shaper spindle.
The spindle 21 is mounted in bearings 22 on the frame 20, and has a flanged belt pulley 23 secured thereto, one end of this spindle has a hub 24 with a threaded opening therein to receive the threaded end ofa shouldered extension 21 which is pinioned to the hub as shown. Between the shoulder and a nut 25 is mounted a saw 26 and its clamp plates 27. i
The frame 20 has a segmental projection 28 which is slotted, as at 29, and extending through the slot is a clamping bolt 31, which passes through a lug on the vertical slide 30 and clamps the segment in any position in which the frame 20 is adjusted, so that if the machine is to be used as a saw, then the frame 20 is moved so that the spindle 21 will be in a horizontal position, as in Fig. 5. l Vhen the frame is in this position a second clamping bolt 76 may be used to clamp the overhanging end of the frame to the slide 80, but should it be used as a shaper, then the clamping bolt 31 is released, and the bolt 76 entirely removed, then the frame 20 is turned on its pivot 19 so that its spindle 21 will assume a vertical In some instances, the vertical slide may be slotted, as at 29, Fig. 11, and a clamping bolt 31 may be mounted on a lug of the frame 20 and adapted to the slot in the slide, without departing from the essential feature of the invention.
At the outer end of the segment 28 is a set screw 32 which bears against the face of the slide 80. By adjusting this set screw before clampingthe frame 20 to the slide,
position, as in Fig. 6.
the saw 26 extends, and lugs 35' the spindle 21 can be accurately adjusted to its horizontal position, and on the frame 20 is a set screw 33 which bears against the inner side of theslide 30, as shown in Fig. 6, so as to adjust the spindle to its vertical position. j Y 7 The table 6 has a slot 34 through whlch project under the slot so as to receive a detachable filling block 36, having a narrow slot for the saw. The saw table has an opening 37 through which the in the vertical position, and thewalls of this openingare shouldered so as to receive a removable block 38 having an opening for the passage of the spinole.
On the vertical slide 30 is an internally threaded lug 65, and passing through the lug is an adjusting screw 66, and on one of the side frames 8 is a bearing 67 through which the screwv extends. On the upper end of the screw is a bevel wheel 68 meshing with a bevel wheel 69 on a horizontal shaft '70 having a hand-wheel 7 1, which is above the hand-wheel for operating the table. On turning the hand-wheel 71, the vertical slide with its spindle can be raised and lowered as desired. The slide 30 is adapted to guideways 7 2 on the standard 1, as shown.
At one side of the'standard 1 is a base 39 having bearings 40 for a driving shaft il. On one end ofthis driving shaft. are fast 1 and'loose pulleys 42 and 43, and at the op- 'posite end is a single pulley lt'fixed to the shaft, and a belt 75 passes around this pulley and around the pulley 23 on the spindle 21, as clearly shown inFig. 1, when said spindle is in its horizontaliposition and the drive is direct, as it isnot necessaryto re verse the spindle "21 when the machine-is used as a saw. 7 v I On an upright l5 is a vertical spindle 46 passing through bearings 17 on the upright, and carried by this spindle is a frame -18 having bearings 49 for'a vertical shaft 50 carrying at its lower end a cone friction wheel 51, and on the shaft 41- are cone friction wheels 52 and 53. On the shaft 50 is a pulley 54, and the belt 7 5 passes around this pulley and around the pulley 23 on the spindle21 when the spindle is in the vertical position, and the parts are so designed that the same belt 75 can be used when the spindle 21 is in either of its two positions.
Secured to the spindle 41 6 isanarm 55, which is connected by a link 56'to an arm 57 son a rock shaft 58 extending from the shift- I iing mechanism to a position in front of the machine so that it can be operated and the frame 48 shifted by the operators foot. The shaft 58 is mounted in a bearing 59 secured to the base of the frame 1, and onthis bearing are ratchet teeth 60 and 61, and se cured to the-end of the shaft 58'is a twoarmed lever 62 having pawls 63 pivotally spindle 21 extends when mounted thereon, and a spring 6 L tends to draw the pawls toward the ratchet teeth 60 and 61, so that by pressing the foot on one lever, the frame &8 can be shifted to one side and its cone wheel 51 will come into frictional contact with the cone 52 on the shaft 41. When the foot is placed on the other pawl 63', the cone wheel 51 will be shifted so as to come into frictional contact with the cone 53, and the rotation'of the shaft 50' will be reversed. When the parts are in mid position, as in Fig. 8, the frame 18 will also be in mid position, and the cone and also to provide means for readily reversing the spindle when it is used as a shaper. The spindle 21 can be adjusted to any angle desired and firmly locked in position after adjustment, and the driving mechanism is so designed that a single belt can be used for driving the spindle in any of its positions. i
